摘要
重载铁路多运行于山区、隧道和长大坡道,能耗和供电品质问题突出,主要表现在用电量大的同时电能损失率也较高,电能质量问题较为严重。本文针对该问题,提出一种重载铁路牵引供电系统“机车-牵引供电网络-地面数据中心”一体化的能耗与供电品质监测系统,通过实时采集电力机车及牵引供电网络的实时同步电气数据,利用通信网络将数据传输至地面数据中心,并通过数据管理软件进行数据的可视化展示,实现重载铁路牵引供电系统“车-网”电气数据的同步监测与综合评估。
Heavy haul railways often cross through mountainous areas,tunnels,and long slopes,with prominent problems of energy consumption and power supply quality,mainly manifested in high electricity consumption and high-power loss rate,resulting in serious power quality problems.With regard to this problem,the paper puts forward an integrated energy consumption and power supply quality monitoring system of the heavy haul railway traction power supply system of"locomotive-traction power supply network-ground data center".Through real-time acquisition of real-time synchronous electrical data of electric locomotive and traction power supply network,it is able to transmit the data to the ground data center via communication network,display visually through the data management software,realize synchronous monitoring and comprehensive evaluation of the electrical data of the"train network"in the traction power supply system of heavy haul railway.
